Control of a Permanent Magnet Synchronous Motor in Simulink

Abstract Nowadays, before the era of modern Steer-by-wire steering systems, most widely used technology is Electric Power Steering (EPS). This paper contains developing a Permanent Magnet Synchronous Motor (PMSM) control circuit for EPS in Matlab Simulink environment. The mathematical model was created via four equations that represent relation between fluxes, voltages and currents d-q reference frame motor torque equation. Mathematical transformations are required to generate equivalent input values from analog waves. In this way, embedded software able communicate with through output signals. also tested physically implemented system. executed on dSpace AutoBox hardware. interface block creates phase specified by module, allows generated voltage be measured back.
